Adrienne Maloof

Show: TheReal Housewives of Beverly Hills

Appearances: Seasons 1, 2 and 3

Reason for Leaving: After Brandi Glanville revealed Maloof's twins were born via surrogate, she alienated herself from the cast — all while her marriage to Dr.Paul Nasssif was ending. In 2014, Maloof said she will make cameo appearances in season 5 to "mend and come full circle."
